IMPROVEMENT IN PUMP STOCKS AND PLUNGERS.

Specification forming part of Letters Patent No. 194,639, dated August 28,1877 application filed August 17, 1877. j

To all whom a may concern.-

Be it known that I, WILLIAM G. BARKER, of Horseheads, in the county of Ohemung, and in the State of New York, have invented certain new and useful Improvements in Pumps; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in the construction and arrangement of a pump, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, refer-. ring to the-annexed drawings, in which Figure 1 is a vertical section of my pump. Fig. 2 is a side view of the same, and Fig. 3 is a detailed view of the pump-plunger.

A A represent two sections of the ordinary wooden pump-tubing, between which the cylinder B is clamped, as hereinafter described.

The cylinder B maybe made of metal, glass, wood, or any other suitable material.

The upper end of this cylinder is inserted in a groove in the lower end of the upper stock section A, and the lower end of the cylinder is inserted in a similar groove in the upper end of the lower section A; but around the lower end of the cylinder B is formed a projecting flange, b, under which is placed a packing-ring, it, against the upper surface of said lower section A, to make an air-tight joint at this point. At the upper end of the cylinder no such air-tight joint is needed, though one maybe applied if de sired.

To the upper stock section A, on opposite sides, are, by bolts 01 d, fastened two coupling.- boards, 0 C, the lower ends of which fit between the projecting ends of bars D D let in to the lower stock-section A, and fastened thereto by bolts 6 e.

A wire, h, is passed through each board (3, as shown, and the ends of said wire bent downward and passed through the ends of the bars D D. Nuts t'"i-are then screwed upon theends of the wire b and, by tightening said nuts, the parts are drawn together, so as to clamp the cylinder B between the two sections A A.

E represents the plungerrod, attached to the plunger in any suitable manner. ln the drawing I have shown the plunger made in two parts, G and G both in circular form, and the upper part or ring Gr provided with a central cross-bar, G in which the plunger-rod is fastened. The two parts G G are connected by means of bolts m m, around which are placed sleeves pp, to hold the parts a proper distance apart, and nuts n n, screwed on the ends of the bolts, unite and hold the parts firmly together.

The parts G and G may, however, if desired, be cast or otherwise made in one piece. In the inner faces of the parts or rings G G are made circular concentric grooves 00 .10, forming bevels or inclines, as shown in Fig. 3, and

in said grooves is inserted a cylinder or broad ring, H, of rubber, leather, or other suitable material, which is held or clamped between the rings in such a manneras to bulge outward and fill and fit the interior of the cylinder B.

v On top of the plunger is an ordinary sliding valve, I, as shown.

When the plunger body G G is made in two parts, one part may be provided with a projecting barrel, and the other part screwed thereon, to hold and clamp the ring H.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with the stocksections A A and cylinder B, the coupling boards 0 0, bars D I), bent rods h h, and nuts it, all substantially as and for the purposes herein set forth.

2. A pump plunger consisting of the rings G G having circular grooves mm, the ring G provided with cross-bar G and the cylinder or ring H held between them, substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 16th day of August, 1677.
